GENERAL BACKGROUND

1. Field of the Invention

The present invention generally relates to an orthodontic connectorassembly and to a method for treating teeth and more particularly, to anassembly which allows orthodontic brackets, even a plurality ofdissimilar brackets, to be selectively and removably coupled to teeth ina manner which forms a method for effectively and therapeuticallytreating teeth.

2. Background of the Invention

Orthodontic brackets, often referred to as “braces”, are devices whichare normally and selectively affixed to the teeth of an individual, bythe use of cement or another type of bonding agent, and are adapted toselectively receive a wire which is formed and deployed in the brackets(e.g., in the mouth of a patient) in order to provide therapeutic forceor pressure on the patient's teeth. The combination of the brackets andthe wire are often sometimes collectively referred to as a “retainingsystem” or an “orthodontic retaining system”.

While such prior and currently utilized retaining systems do allowtherapeutic pressure to be applied to a patient's teeth, they sufferfrom some drawbacks.

By way of example and without limitation, as the therapy is applied tothe patient (i.e., over time) modifications may need to be made to thebrackets or different brackets may be optimally needed. This “bracketmodification” or “replacement” is complicated and time consuming becausethe currently utilized brackets must be forcibly removed from thepatient's teeth (e.g., removed from the cement or adhering agent), theteeth must be cleaned and “re-prepped” (an etching agent and a newapplication of an adhering agent must be deployed on the teeth), and thenew or modified brackets must be deployed on the newly prepped teeth.The process is uncomfortable to the patient and is relatively costly dueto the need for additional etching and adhesive material and the timeneeded to achieve the change or modification. Moreover, sometimes thedeployed brackets become broken or are in need of repair and must beremoved from the patient's teeth to become serviced, thereby requiringthe same sort of afore-described process and relatively the same sort ofcost and discomfort.

Further, it may be therapeutically desirable to deploy different sortsor types of brackets upon the teeth of a patient within a relativelyshort amount of time due to the needs of the patient and such “rapidbracket deployment” undesirably and greatly increases the cost anddiscomfort to the patient. Further, different sorts of brackets may beused on a patient, within a certain time, just in order for aorthodontist to evaluate the efficacy of these deployed brackets on acertain patient and discover the bracket type which may provide optimaltherapy on a particular patient (i.e., each patient may experiencedifferent amounts and types of therapy with a certain bracket).Non-limiting examples of orthodontic brackets are found within UnitedStates Patent Application Publication Numbers US2005/0255422 A1,US2002/0058227 A1, and US2004/0157184 A1 which are each fully andcompletely incorporated herein by reference, word for word and paragraphfor paragraph.

There is therefore a need for a new and improved connector assemblywhich allows brackets and orthodontic retaining systems to be easily,quickly, and cost effectively deployed upon the teeth of a patient andit is one non-limiting object of the present invention to provide suchan improved connector system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

Referring now to FIGS. 1, 2, 3, and 6, there is shown an orthodonticconnector assembly 10 which is made in accordance with the teachings ofthe preferred embodiment of the invention.

Particularly, the orthodontic connector assembly 10 includes a pluralityof substantially identical connector members, such as members 12, 14,which may be constructed from metal, plastic or another compositematerial and which includes a first substantially flat back surface 16and a second substantially flat front surface 18. The connector members,such as members 12, 14, are of a size and a shape which is smaller thanthe size and shape of a human tooth. Nothing in this description ismeant to limit the members 12, 14 to any particular size and shape or toany particular material and, in various alternate embodiments of theinvention, many connector members of different sizes and shapes may beprovided.

The surface 18 includes a portion 20 which is hingedly coupled (e.g., bya hinge member 3 which is coupled to surface 18 and to member 20) to thesurface 18 along the edge 22 and thus normally contacts (i.e., is biasedagainst) surface 18 but may be selectively moved from this first surfacecontacting position to a second non-contacting position away fromsurfaces 18 and 16. In one non-limiting embodiment, hinge member 3 mayspace a spring or other device which allows portion 20 to be selectivelyand movably coupled to surface 18 but which causes portion 20 to bebiased against surface 18. Portion 20 may be of substantially anydesired shape. The surface 18 further includes a raised edge portion 30upon which the far edge 32 of portion 20 overlays (e.g., the term “faredge”, in this context, means the part of portion 20 farthest away formedge 22).

The connector assembly 10 further includes at least one bracket 40having a generally flat back surface 42 upon which a pocket portion 44is formed. A pocket portion 44 may comprise a generally “c-shape” memberwhich is coupled to the surface 42 and which includes an opening 43which extends through the entire pocket portion 44 and which liesbetween surface 42 and inner surface 5 of the portion 44. The at leastone bracket 40 may have a front portion 41 of any desired size and shapetherapeutic configuration and the pocket portion 44 is adapted toreceive the portion 20, of a member 12, after it is raised off of thesurface 18 that it normally is biased against by the edge 22 (e.g., themember 20 is selectively received within and extends through opening 43in a manner which allows surface 41 to cover the portion 44 from view).The pocket portion 44 may be integrally formed with bracket 40 orattached to bracket 40 by adhesive or any other similar type ofmaterial.

The front portion 41 may be adapted to receive a wire or any othertherapeutic member or element. After the pocket 44 receives the raisedportion 20 (e.g., the portion 20 is inserted through opening 43 of thepocket portion 44) it is ensured that the bottom edge 50 of the pocketportion 44 is supported by edge 30 and then the raised portion 20 isallowed to be biased back toward surface 18 by the biasing member 22,thereby fixing the pocket portion 44 against the surface 18 andattaching the bracket 40 to the portion 12, as shown best in FIG. 6. Theedge 30 cooperates with the edge 50 to further attach the bracket 40 tothe member 12. It should be appreciated that bracket, such as bracket70, which may be dissimilar to bracket 40, is made to have asubstantially identical back surface 72 which is similar to back surface41 (i.e., each dissimilar bracket is made to have a substantiallysimilar back surface and thereby includes a substantially identicalpocket 44). Thus, every bracket to be utilized as part of or incombination with the assembly 10 must, in the most preferred althoughnon-limiting embodiment, include a back portion which is substantiallysimilar to back portions 42, 72 (e.g., having a pocket portion 44) butwhich may have a respectively unique and therapeutic front portion(i.e., a portion which receives a wire). In this manner, the respectivetherapeutic front portion (e.g., portion 41) always outwardly extendsfrom the front surface 7 of each tooth (e.g., the surface which isvisible, in the manner which is shown, for example, in FIGS. 3 and 6.Thus, a first set of substantially identical brackets (one for eachtooth to be treated) may be deployed, such that each bracket is deployedupon a unique tooth 9, 11 within the mouth of a patient (e.g., each ofthese brackets has a substantially identical front portion 41 andsubstantially identical back portion 42). A second set of brackets, eachhaving a front portion which is dissimilar to the front portion of thefirst set of brackets, may replace the first set of brackets, if theneed arises. Alternatively, dissimilar brackets (e.g., those havingrespectively different therapeutic front portions) may be concurrentlyutilized upon various teeth within the mouth of a patient if the needarises.

The connector assembly 10 may also include a quantity of cement or anadhesive 80 and some etching material or acid 82. In other non-limitingembodiments of the invention, the assembly 10 does not include theadhesive 80 or etching material 82 or any brackets, such as bracket 40.

As shown best in FIGS. 2 and 3, teeth, such as teeth 7, 9, which are toreceive the substantially identical members, such as members 12, 14, arefirst etched with the material 82 and then the attaching material 80 isapplied to the previously etched teeth and then the respective surface16 of each respective member 12, 14 is placed onto a respectively uniquetooth 7, 9 (i.e., onto the previously deployed material 80), until allof teeth 7,9 which are to be therapeutically manipulated have received aunique member 12.

Brackets, such as bracket 40 may be easily applied and removed from eachof the deployed members 12 (e.g., a bracket, such as bracket 40 isremoved simply by moving the portion 20 away from the surface 18 andsliding the pocket 44 downwards in the direction 90). In this manner,brackets, such as bracket 40, may be easily applied and removed fromteeth.

Thus, it should be appreciated that this forgoing invention describes asystem and a technique by which dissimilar brackets are made to have acommon back portion 42, 72 which is adapted to selectively and removablyreceive a standardized member 12, 14 which has been placed upon teeth.In this manner, dissimilar brackets (e.g., those with differenttherapeutic or “wire receiving” frontal portions 41) may be easilyplaced upon and removed from teeth (e.g., front portion 20). It shouldalso be appreciated that the shape of portions 20 and pocket 44 maychange as desired and that nothing in this description is meant to limitthe shape of portion 20 in any manner.

Referring now to FIG. 4-5, there is shown a connector member 200 whichis made in accordance with the teachings of an alternate embodiment ofthe invention and which includes a substantially flat base portion 202having a flat back surface 204 which is adapted to be selectivelyattached to a tooth, such as tooth 206, such as by use of attachingmaterial 80. The member 202 has a substantially flat front surface 210having a protruding central ridge portion 212 which protrudes away fromsurfaces 210 and 204, and from tooth 206 when the member 202 isselectively attached to the tooth 206 (e.g., by use of cement/glue).

The bracket, such as bracket 230, has a therapeutic front portion 232,which may be configured as desired and which is selectively adapted toreceive wire, such as wire 353, and a back portion 234 having adepression or slot 236 which is adapted to selectively and removably andfixedly receive the member 212 (e.g., the slot 236 selectively “slidesonto” and frictionally engages and receives member 212), therebyallowing the back surface 234 to be slidably, frictionally, selectively,and removably fixed onto member 212. In this manner, each tooth, such astooth 206, may receive a connector member 200 and have the connectormember 200 selectively adhered to it, thereby allowing a bracket, suchas bracket 230, to be connected to the member 200 and selectivelyremoved from it (e.g., by having the member 230 selectively and forcibly“slide away” from the ridge 212). The ridge 212 may be of any shapeincluding a columnar shape and the shape of ridge 212 is “complimentary”to the shape of the slot 236 (e.g., the term “complimentary” means aridge 212 is adapted to be selectively, slidably, removably andfrictionally received within a slot 236 and to be later selectively andfrictionally removed from the slot 236).

In yet another non-limiting embodiment of the invention, the slot 236may include at least one ridge 304, which may be placed within and/orformed within the slot 236 and which is adapted to selectively engageedge 310 of ridge member 212 to prevent movement of deployed bracket 230in the direction of arrow 320. In this manner, the deployed bracket,such as bracket 230 may be adjusted to occupy a certain position alonglength 400 of a member 212 but will never move out of engagement withmember 212 while traveling along direction 320. Additionally, arelatively thin wire strap, such as strap 330, may be deployed uponsurface 210 and adapted to be placed around the interior slot portion350 of the bracket 230 after slot 236 receives ridge 212, therebyfurther securing the bracket 230 to the member 210. Therapeutic wire 353may, of course, later be placed within slot 350 (i.e., after strap 330is made to selectively occupy the slot 350).

Referring now to FIGS. 7, 8 and 9, there is shown a bracket 400 which ismade in accordance with the teachings of the invention. Particularly,bracket 400 includes a front surface 402 and a back surface 404 whichmay be substantially similar to back surface or portion 234 which isshown in FIG. 5.

Front surface 402 includes four substantially similar protuberances 406,408, 410, and 412 which cooperatively form a channel 414 in which member416 resides. Particularly, member 416 is pivotally coupled to surface402 by attachment pin 420 or a tack weld and has a width 440 which issubstantially equal to the width of the channel 414 and member 416 has anub or protuberance portion 442 which extends off of and away from thesurface 402 and away from pin 420. In one non-limiting embodiment of theinvention, the nub portion 442 “curls” or projects away from surface 402and toward surface 404.

In operation, the bracket 400 may be attached to the member 212 in themanner which has been previously delineated (e.g., as the back surface404 is placed onto the ridge member 212, the nub 442 is made to forciblypivot away from the surface 402 until the surface 404 is secured ontothe member 212 at which time the nub 442 engages the surface 411 of themember 212 onto which it is deployed). Thus, in this embodiment, thebracket 400 is given additional “stability” (e.g. has a reducedlikelihood of movement off of member 212) due to the fact that nub 442frictionally engages the surface 411 of the member 212, when the bracket400 is attached to member 210, thereby preventing or substantiallyreducing the likelihood of movement of the bracket 400 from surface 210.Further, wire 450 may be placed between the protuberances 406, 408, 410and 412, thereby further securing the bracket 400 to the surface 210 bypreventing disengagement of member 416. When it is desired to remove thebracket 400 from the member 212, the wire 450 is removed, the member 416is pivoted away from the surface 402 (i.e., shown in phantom in FIG. 9),thereby causing nub 442 to be in a “non-contact” relationship with 411portion of 212 and then the back surface of the bracket 400 is “slidaway” from contact with ridge 212 in the direction of arrow 460.

Referring now to FIGS. 10 and 11, there is shown a bracket 500 which ismade in accordance with the teachings of yet another alternateembodiment of the invention.

Particularly, bracket 500 has a front surface 502 which is substantiallysimilar to front surface 402 (e.g., having four substantially similarprotuberances 504 which are similar to each of the protuberances 406,408, 410, 412. However, bracket 500 includes a member 516 which ispivotally coupled, like member 416 to the front surface 502 and whichincludes a member 542 which, like member 442, projects away from surface502. However, unlike member 416, the member 516 additionally includes aprojection 560 which projects away from the front surface 502. Further,unlike member 212, the member 550 includes equidistantly spaced slots,562, 564, 568, 570, 572, and 574, each of which is adapted toselectively and frictionally and removably receive projection 560. Inthis manner, the position of the bracket 500 along axis 600 may beselectively modified (e.g., by selecting which slot 562-574 which is toreceived the projection 568, the position of the bracket 500 along axis600 may be selected).

When it is desired to remove the bracket 500 from the member 210, theprojection 560 is forcibly removed from whatever slot 566-574 itcurrently resides within, the member 542 is moved away from the detent700, and the bracket 500 is slid off the member 210. Nothing in thisdescription limits the invention to any particular number or types ofslots 562, 564, 568, 570, 572, and 574 or to any particular number ortype of members 560.

It is to be understood that the various inventions are not limited tothe exact construction or methodology which has been delineated anywherein this description, but that various changes and modifications may bemade without departing from the spirit and the scope of the inventionsas are delineated in the following claims.
